Pigs following the steers. — To study the comparative value of the 

 droppings from the different lots, 7 pigs followed each lot of steers from 

 December 15 until the close of the test. The amount of grain fed to 

 the pigs in addition is recorded. They were fed the same grains as the 

 steers which they followed. At the beginning the average weight of 

 the pigs following the different lots was 10(3, 108, and 109 lbs., respec- 

 tively. On the basis of the undigested grain as determined above the 

 food consumed, the gains made, and the food consumed per pound of 

 gain were as follows :

It is evident from the table that, though the pigs were fed practically 

 the same amounts of graiu, the gains made vary with the amounts 

 found in the manure. In the authors' opinion the experiment proves 

 that pigs can utilize Kafir corn feed in the manure and bring out the 

 value in pork in about the same ratio of values that exists between 

 corn and Kafir corn. 



The pigs were not all sold, but from available data it was calculated 

 that there would have been a profit of $7.10 for lot 1, $10.12 for lot 2, 

 and $11.21 for lot 3. Records were kept of the mean daily temperature 

 of the yards throughout the whole experiment. 



Feeding lambs, O. F. Curtiss and J. W. Wilson (Iowa Sta. Bui. 

 35, pp. 717-749, Jigs. IS). — In continuation of work previously reported 

 (E. S. R., 9, p. 81) the authors made a feeding experiment with 81 

 wether lambs of the following breeds: Southdown, Shropshire, Oxford, 

 Suffolk, Lincoln, Leicester, Cotswold, Dorset, and Merino, and 10 

 Shropshire ewe lambs. 



The lambs were divided into 7 lots of 9 each, 1 lot of 10, and 1 lot 

 of 8. Most of the lambs were purchased in Canada and arrived at the 

 station during July and August. They were dipped soon after their 

 arrival and put on a timothy and blue grass pasture, and given a light 

 ration of oats and bran in addition. The lambs were given worm 

 powders, which were found to be more of a preventive than a remedy. 

 The general conditions were the same as in the previous experiment. 

 The experiment proper, which was preceded by a preliminary period 

 of 15 days, began December 10 and continued 100 days, the conditions 

 being the same throughout the whole time. 



The lambs were fed all they would eat of a mixed grain ration with 

 roots and hay. During the early part of the test a little green clover
